<h4><a name = "tag_000_010_554">&nbsp;</a>NAME</h4><blockquote>
wcsncmp - compare part of two wide-character strings
</blockquote><h4><a name = "tag_000_010_555">&nbsp;</a>SYNOPSIS</h4><blockquote>
<pre><code>

#include &lt;<a href="wchar.h.html">wchar.h</a>&gt;

int wcsncmp(const wchar_t *<i>ws1</i>, const wchar_t *<i>ws2</i>, size_t <i>n</i>);
</code>
</pre>
</blockquote><h4><a name = "tag_000_010_556">&nbsp;</a>DESCRIPTION</h4><blockquote>
The
<i>wcsncmp()</i>
function compares not more than
<i>n</i>
wide-character codes (wide-character codes that follow a null
wide-character code are not compared) from the array pointed to by
<i>ws1</i>
to the array pointed to by
<i>ws2</i>.
<p>
The sign of a non-zero return value
is determined by the sign of the difference between the values of the
first pair of wide-character codes
that differ in the objects being compared.
</blockquote><h4><a name = "tag_000_010_557">&nbsp;</a>RETURN VALUE</h4><blockquote>
Upon successful completion,
<i>wcsncmp()</i>
returns an integer greater than, equal to or less than 0, if the possibly
null-terminated array pointed to by
<i>ws1</i>
is greater than, equal to or less than
the possibly null-terminated array pointed to by
<i>ws2</i>
respectively.
